Wes Hayden only went on Bachelorette Jillian Harris' season to promote his music career, not to fall in love.

Tim McCormack is remembered for getting kicked off of Ashley Hebert's season during the first cocktail party after he passed out drunk.

Krazy Kasey Kahl attempted the most extreme stunt ever by getting a tattoo to prove his interest in Bachelorette Ali Fedotowsky. Everyone thought he was crazy for doing this!

Justin Rego crushed Bachelorette Ali Fedotowsky when she found out that he had a girlfriend back at home.

Jason Mesnick left his season engaged to Melisss Rycroft — but then dumped her after the show ended to get married to runner-up Molly Malany.

Jake Pavelka crushed all the women on his season when he proposed to vixen Vienna Girardi. He then destroyed their relationship after the show ended because he really wanted to chase a career in Hollywood. Did he ever have the intention of getting married?

Brad Womack, once referred to as the most hated man in America, has been on The Bachelor twice. And the first time he went on — he proved to be a total heartbreaker when he left the show single and didn't propose to either DeAnna Pappas or Jenni Croft.

Bentley Williams is infamous for breaking the heart of Bachelorette Ashley Hebert. He went on the show and lead her on to believe that he was falling in love, but then talked trash about her to the cameras. He then left telling her that he needed to go home because of his daughter, but in reality thought Ashley was an "ugly duckling."

These stars are quite the lookers! But together…they make for some pretty odd couples!

The Bachelor and The Bachelorette are supposed to be series about finding love, but some guys just don’t go on the show for the right reasons. Others just aren’t mature enough or honest enough to get serious with the women they meet. Bentley Williams, Brad Womack, Jake Pavelka, Tim McCormack, Jason Mesnick, Wes Hayden, Kasey Kahl and Justin Rego have all been called out for their bad boy ways — but we want to know who you think is the worst Bachelor of all?
